depending what I for the initial step, with my setting initialSteps=60,
I can save around 50% with the MovieLens10m dataset.
You can also justify this by saying that we are minimizing a function,
so that a fixed number of steps is not really the best way to achieve
this (e.g. depending on the slope it might arrive to the local minima
sooner or later).

How much speedup do you observe?

Hi,
I was looking at the SVD code, I am sure you are aware of this
modification, but it would really make things faster. The idea is that you
set up a minimum RMSE improvement so it would stop training a particular
feature if the algorithm reaches that threshold. I implemented it based on
your code, it is just a slight change.
